How do I mount a PersistentVolume using the Kong Helm Chart?
Declare the volume under deployment.userDefinedVolumes and deployment.userDefinedVolumeMounts in your Helm values.yaml (for example, referencing a PersistentVolumeClaim) so it’s mounted in all Kong containers. The PV and PVC must already exist in Kubernetes, or the pods will wait indefinitely for the claim.
Steps
To mount a PersistentVolume, you need to declare the volume in the deployment.userDefinedVolumes and deployment.userDefinedVolumeMounts sections. You can find the details in the documentation.
After declaring the userDefinedVolumes and userDefinedVolumeMounts, the volume will be mounted in all the Kong containers.
If you want to use a PersistentVolumeClaim, you can declare it in the same way as an emptyDir, but you must create the PV and PVC claim in Kubernetes, otherwise the pods will not be created, waiting for the PVC. You can find the details in the Kubernetes docs.
As an example, the values.yaml file will be like:
deployment:
# Define any volumes and mounts you want present in the Kong proxy container
userDefinedVolumes:
- name: "test-volume"
persistentVolumeClaim:
claimName: myclaim
userDefinedVolumeMounts:
- name: "test-volume"
mountPath: "/tmp/kong_volumes/mount"Assuming the PVC myclaim exists in the Kong namespace.
